pub struct RadiusOptions { /* private fields */ }
Expand description

Options for the GEORADIUS and GEORADIUSBYMEMBER commands

Example

use redis::{Commands, RedisResult};
use redis::geo::{RadiusSearchResult, RadiusOptions, RadiusOrder, Unit};
fn nearest_in_radius(
    con: &mut redis::Connection,
    key: &str,
    longitude: f64,
    latitude: f64,
    meters: f64,
    limit: usize,
) -> RedisResult<Vec<RadiusSearchResult>> {
    let opts = RadiusOptions::default()
        .order(RadiusOrder::Asc)
        .limit(limit);
    con.geo_radius(key, longitude, latitude, meters, Unit::Meters, opts)
}

Implementations

Limit the results to the first N matching items.

Return the distance of the returned items from the specified center. The distance is returned in the same unit as the unit specified as the radius argument of the command.

Return the longitude, latitude coordinates of the matching items.

Sort the returned items

Store the results in a sorted set at key, instead of returning them.

This feature can’t be used with any with_* method.

Store the results in a sorted set at key, with the distance from the center as its score. This feature can’t be used with any with_* method.

Trait Implementations

Returns the “default value” for a type. Read more

This writes the value into a vector of bytes. Each item is a single argument. Most items generate a single item. Read more

Returns an indiciation if the value contained is exactly one argument. It returns false if it’s zero or more than one. This is used in some high level functions to intelligently switch between GET and MGET variants. Read more

This converts the value into a vector of bytes. Each item is a single argument. Most items generate a vector of a single item. Read more

Returns an information about the contained value with regards to it’s numeric behavior in a redis context. This is used in some high level concepts to switch between different implementations of redis functions (for instance INCR vs INCRBYFLOAT). Read more

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.
